如何使 jquery 照片库滑块与重复滑块一起玩得很好？

Question

首先，我对 j-query 很陌生。话虽如此，我有一个非常简单的 j-query 照片画廊滑块，它可以保存图像并每隔几秒钟淡入新的图像。我有一个页面，我复制了它，并在 js 中给它不同的 css 和 class/id 名称以制作不同的名称。我希望两者都在同一页面上。现在我已经启动了第二个并完美运行。即使它们共享不同的 css、html 和 j-query 脚本，也会导致第一个无法工作

这是第一个的所有代码：

j-查询：

<script type="text/javascript">

function theRotator() {
    //Set the opacity of all images to 0
    $('div#rotator ul li').css({opacity: 0.0});

    //Get the first image and display it (gets set to full opacity)
    $('div#rotator ul li:first').css({opacity: 1.0});

    //Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds
    setInterval('rotate()',10000);

}

function rotate() { 
    //Get the first image
    var current = ($('div#rotator ul li.show')?  $('div#rotator ul li.show') : $('div#rotator ul li:first'));

    //Get next image, when it reaches the end, rotate it back to the first image
    var next = ((current.next().length) ? ((current.next().hasClass('show')) ? $('div#rotator ul li:first') :current.next()) : $('div#rotator ul li:first'));   

    //Set the fade in effect for the next image, the show class has higher z-index
    next.css({opacity: 0.0})
    .addClass('show')
    .animate({opacity: 1.0}, 1000);

    //Hide the current image
    current.animate({opacity: 0.0}, 1000)
    .removeClass('show');

};

$(document).ready(function() {      
    //Load the slideshow
    theRotator();
});

</script>

html:

<div id="new_home_photo" class="round_10px">
    <div id="rotator">
        <ul>
            <li class="show">
                <a href="javascript:void(0)">
                    <div id="photo_1" class="round_7px">
                    </div>
                </a>
            </li>
            <li>
                <a href="javascript:void(0)">
                    <div id="photo_2" class="round_7px">
                    </div>
                </a>
            </li>
            <li>
                <a href="javascript:void(0)">
                    <div id="photo_3" class="round_7px">
                    </div>
                </a>
            </li>
        </ul>
    </div>
</div>

CSS：

/* rotator in-page placement */
div#rotator {position:relative;height:345px;margin-left:0px;}

/* rotator css */
div#rotator ul li {float:left;position:absolute;list-style:none;}

/* rotator image style */   
div#rotator ul li img {vertical-align:left;}

div#rotator ul li.show {z-index:500;}

#photo_1 {background:url(images/home_actual_1.jpg)no-repeat; width:621px;height:420px;}

#photo_2 {background:url(images/home_actual_2.jpg)no-repeat; width:621px;height:420px;}

#photo_3 {background:url(images/home_actual_3.jpg)no-repeat; width:621px;height:420px;}

这是第二个正在工作并导致第一个停止工作：

j-查询：

<script type="text/javascript">

function theRotator() {
    //Set the opacity of all images to 0
    $('div#rotator_update ul li').css({opacity: 0.0});

    //Get the first image and display it (gets set to full opacity)
    $('div#rotator_update ul li:first').css({opacity: 1.0});

    //Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds
    setInterval('rotate()',10000);

}

function rotate() { 
    //Get the first image
    var current = ($('div#rotator_update ul li.show_update')?  $('div#rotator_update ul li.show_update') : $('div#rotator_update ul li:first'));

    //Get next image, when it reaches the end, rotate it back to the first image
    var next = ((current.next().length) ? ((current.next().hasClass('show_update')) ? $('div#rotator_update ul li:first') :current.next()) : $('div#rotator_update ul li:first'));  

    //Set the fade in effect for the next image, the show class has higher z-index
    next.css({opacity: 0.0})
    .addClass('show_update')
    .animate({opacity: 1.0}, 1000);

    //Hide the current image
    current.animate({opacity: 0.0}, 1000)
    .removeClass('show_update');

};

$(document).ready(function() {      
    //Load the slideshow
    theRotator();
});

</script>

#update_3 a:hover {color:#F16C22;}

我也尝试了许多重命名类和共享类的组合，但没有什么能导致它们同时工作。

提前非常感谢！

问题是您的函数名称仍然相同（即 theRotator 和 rotate 在页面中出现两次），这导致了问题。

最好的解决方案是更改您的 theRotator 和 rotate 方法，以便您可以传入要旋转的任何幻灯片的 ID。比如：

function theRotator(sliderId) {
    //Set the opacity of all images to 0
    $('div#' + sliderId + 'ul li').css({opacity: 0.0});

    //Get the first image and display it (gets set to full opacity)
    $('div#' + sliderId + ' ul li:first').css({opacity: 1.0});

    //Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds
    setInterval('rotate(' + sliderId + ')',10000);
}

function rotate(sliderId) { 
    //Get the first image
    var current = ($('div#' + sliderId + 'ul li.show')?  $('div#' + sliderId + ' ul li.show') : $('div#' + sliderId + ' ul li:first'));

    ...
};

$(document).ready(function() {      
    //Load the slideshows
    theRotator('rotator');
    theRotator('rotator_update');
});
